Why does my heart beat faster after drinking alcohol?

Many people always talk about things over a drink, especially when some men meet each other, they always clink glasses and drink to their heart's content. However, many people find that their heartbeat accelerates after drinking. Most people cannot explain the reasons for this phenomenon very well. Let me give you a detailed introduction to the principle of accelerated heartbeat after drinking!

After drinking, the body will speed up blood circulation in order to consume and dissolve alcohol to quickly achieve the purpose of dissolution. It usually manifests as accelerated heartbeat, sometimes dull pain, and accompanied by blushing.

The reason why your heart beats faster after drinking:

We all know that the mechanism that controls the speed of a person's heartbeat is as follows: there is a sinoatrial node at the root of the aorta, which sends out electrical stimulation autonomously and at a regular interval. The current is transmitted to the myocardium through the conduction bundle, causing myocardial contraction. At the same time, the medulla oblongata in the central nervous system is the heartbeat center, which sends out sympathetic nerves that speed up the heartbeat and vagus nerves that slow down the heartbeat.

Normally, the sympathetic and vagus nerves are in a state of balance. However, after drinking, the sympathetic nerves are excited due to the stimulation of alcohol, which causes the heartbeat to speed up, thereby increasing the amount of blood pumped by the heart per minute and supplying more blood to the body to cope with the crisis; in this way, the heart beats more frequently, which is manifested in a faster heartbeat!

In addition to drinking, a person's heart rate can also increase in many other situations, for example, from sleeping to awake, from stationary to exercising, from a low-exercise state such as walking to a high-exercise state such as running; in addition, from lying to sitting or standing, and from sitting to standing, because the heart needs to raise the blood pressure to a higher level, the heart rate also needs to increase, and the heart rate increases!

Why do people feel sleepy when their heart rate increases?

A large amount of blood flows back to the heart, and then is pumped out to the whole body by the heart. In this process, a large amount of blood flows back to the heart, so the brain is relatively ischemic and hypoxic. Therefore, some people will feel sleepy and drowsy.

The feeling of wanting to sleep can also occur after meals. After a full meal, a large amount of blood flows back to the stomach to help digestion, causing the brain to be deprived of blood and oxygen. Therefore, some people also feel sleepy after meals.

From the above, we can see that the increased heartbeat is mainly caused by the stimulation of alcohol. In order to digest and dissolve alcohol, the body will mostly show an accelerated heartbeat. Therefore, when drinking, it is best to stop drinking and not drink excessively. If you drink too much, it will not only cause physical discomfort, but in severe cases it may also lead to alcoholic fatty liver.
